Be it known that I, 'LnANn'aR W. Noon, a citizen of the UnitedStates,"an d"resident of Fontanelle, in'the county of Adair and-State ofIowa, have, inventeda' certain new and useful Tire, of which thefollowing is a specification. 4 o

The object of n1y'i iventionis to: provide a resilient'tire for vehiclewheelsoffsiin'ple, durable and inexpensiveconstruction. Moreparticularly it is my object 'to pro vide a tire of the kind mentionedpreferably made of rubber, designed to taketheplac'e of a pneumatictirecomprisingl continuous solid rubber tire, fhaving an' 'exteriorannular central groove .with aresilient ad-j just-able metal bandtherein." j a Still a furtherobjectlis to provide aftire of thegeneraltype mentioned, in 'its tread surfaces, transverse grooves orwalls of peculiar form adapted to give a better grippingztread member,and td- 'fa cilitate easiertravel.

Vith these and other objects in view,"my'

invention consists in the construction, arrangement and combination ofthe various parts of the device, whereby the objects contemplated areattained, as hereinafter more fully set forth, pointed out in my claimsand illustrated in the accompanying drawings, in which:

Fi ure 1 shows a side elevation ofa wheel" 2'3 equipped with a tireembodying my 1nvention, a portion of the tire being shown in crosssection.

Fig. 2 shows a transverse, sectional view through the rim of the wheel,with the tire installed thereon; and a Fig. 8 is a detailed view of aslightly modified form of my invention.

In the accompanying drawings, 1 have used the reference numeral 10 toindicate generally a vehicle wheel having the rim 11. My improved tirecomprises an annular 1 rubber tire A. having a longitudinal, cenfromtheir outer edges toward the center of the wheel, as at 15. The innerportion of bolt 23 and nut 24.

the tire projects inwardly and sets'onthe run 11 between two'metal'rings 1-6, which are bolted to the rim and project radially outwardlytherefrom into rabbets 17 at the sides ofx'the tire, as clearlyillustrated in --Extendedthrough the tire and projecting radiallyinwardly therefrom are bolts- 18,

which 'exte nd' through the rimand are fasten'edtheret'o; f'The heads19;of the bolts 18 andthe'washers20iadjacent to said heads eraser intothe :tire at'the bottom ofth'e groove '12. Snuglyreceived in the bottomof the grooiu-i-"12'isan annular, resilient metal band orringi21,*-having its adjacent ends' provided w th oppositely extendingflanges 22,Wl11,0l1 are ad ustably connected together by means of atom-23- and anut 2d. The

1 3 1 21 53" g i x the installation of thetire onthe wheel, one of "therings '16" may be removed'and band 251' is a widefiat' ba'nd asshown inthetire'may then be slid onto the rim. The I tire in ay be stretched orsprung sufficiently for permitting thein'sertion of the inner onds ofthe bolts 18 through the holes in the rim. The nuts may then :beassembledon the bolts 18. The flange 16 is placed in po sition andfastened by means of the bolts and nuts provided therefor.

Thering or band 21 isthen sprung sufficiently to mount it on the tire inthe groove I 12, and thereafter the ends ofthe band 21" are drawntightly together by means of the The tire may be provided with reinforceing wires or the like 25. I preferably pro vide the tire at its outerradial edges with reinforcing wires 26.

The tire is'broader at its outer tread portion than at its portionadapted to fit the rim, and has the circumferential, central,

. annular, external groove, the walls of which are inclined from theperpendicular, as shown inthe drawings The groove is narrower at itsbottom than at its outer portion, and the tread portion of the tire isinclined from the edge of said groove laterally and radially outwardly,asillustrated. It .will be seen that on account of the beveled edgesHand the groove 12, I have rovided a tire which will not easily skid.*urthermore, the shape of said beveled surfaces is such as to reduce theshock of traveling on rough roads. In traveling over the ground with thetire of this type, a Will be seen that Where the tire travels overpebbles or small stones, the shock will not be readily transmittedrthrough*the wheels,

but Will tend to be distributed over the rub- V ber tire.

It will be noted that on account of the arrangement of the beveledsurtac'es l lythe relative sharp, outeredges of the tire will engage theskidding. y

In Fig. 3, I 'ha'veshown a slightly modifiediforin of the invention, inwhich the treadsurfaces of the tireiare provided with ground forpreventing any side cross rgrooves or slots 30,;each preferably havingone Wall arranged substantially radially of the wheel and the -otherbeveled; as illustrated in Eig.- 3. yThesegrooves :serve a :doublepurpose. They afford gripping members fortraveling 'ingthe mud or thelike,(particularly-on account of the arrangeg menti of the Wallso-f-thegr ooves BO hich serve :to ;grip the ground when the Wheeltravels. inthe direction indicated-by the arrow inEig. 3. fllhesegmovsalso serve to cushion the aetionof the Wheel, j ustras do the beveled-surfaces 1'14. f x r I Somechanges maysbe made in the construction .andarrangement of my improved tire Without departing from the real spiritand purpose otmy invention and itais my intention to .cover by my claimsany modified forms of structure ,or use. of mechani caliequivalents,which may be reasonably ,includedwithin theirtseope.
